So on here when your trying to learn kanji, how come for the kunyomi has about 4 different ways you can say the kanji. And sense theres about 4 diffrent ways you can say them which one do are you supposed to memorize because learning the strokes with all the different kunyomi readings and onyomi reads is just way to much. So am I only supposed to study one of them or do I have to memorize all of the kunyomi?
